This category contains results about Real-Valued Functions.
Definitions specific to this category can be found in Definitions/Real-Valued Functions.
Let $f: S \to T$ be a function.
Let $S_1 \subseteq S$ such that $\map f {S_1} \subseteq \R$.
Then $f$ is said to be real-valued on $S_1$.
That is, $f$ is defined as real-valued on $S_1$ if and only if the image of $S_1$ under $f$ lies entirely within the set of real numbers $\R$.
A real-valued function is a function $f: S \to \R$ whose codomain is the set of real numbers $\R$.
That is, $f$ is real-valued if and only if it is real-valued over its entire domain.
